WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect,
for example, the power steering and the brake boosting effect. You will require considerably
more effort to steer and brake. There is a risk
of an accident.
Do not switch off the ignition while driving.
ECO display
ECO display (example)
The ECO display gives you information on how
economical your driving style is. The ECO dis-
play assists you in achieving the optimum
driving style in terms of consumption, taking
the actual and selected conditions into con-
sideration. Your driving style can significantly
influence the vehicle's consumption.
The ECO display consists of three bars:
R
Acceleration
R Constant
R Coasting
The percen tvalue is the average value of the
three bars .The three bars and the average
value commence with a value of 50%. Ahigher
percentage indicates a mor eeconomical driv-
ing style.
The ECO display provides no information on
the actual fuel consumption. Afixed percent-
age value of the ECO display does not corre-
spond to a fixed consumption figure in
l/100km.
Apart from driving style, consumption is
dependent on many factors such as:
R load
R tyre pressure
R cold start
R selected route
R number of consumers that are switched on Driving tips

work on the battery carried out at a qualified
specialist workshop. G
WARNING
Work carried out incorrectly on the battery
can, for example, lead to a short circuit and
damage your vehicle's electroni csystem. This
can disrupt driving safet ysystems such as
ABS (anti-lock brakin gsystem) or ESP ®
(Elec-
tronic Stability Program).
R If ABS malfunctions, the wheels can lock
during braking. This limits the steerability
of the vehicle when braking and the braking
distance may increase .There is a risk of
accident.
R If ESP ®
malfunctions, the vehicle will not be
stabilised if it starts to skid or a wheel starts
to spin. There is a risk of accident.
You should therefore have all work involving
the battery carried out at a qualified specialist
workshop. G
WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture is formed
when charging the battery or jump-starting.
Always make sure that neither you nor the
battery is electrostatically charged. For
example, electrostatic charge is caused by:
R wearing synthetic clothing.
R the friction of clothing on the seat.
R pulling or pushing the battery over carpets
or other synthetic materials.
R wiping the battery using a cloth. G
WARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
R
Make sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
R Never place metal objectsort ools on a bat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting a battery.
R When jump-starting, make sure that the
battery poles with identical polarity are
connected.
R It is particularly important to observe the
described order when connecting and dis-
connecting the jump leads.
R Never connect or disconnect the battery
terminals while the engine is running. G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention. H
Environmental note Batteries contain pollutants.
It is illegal to dispose of them
with the household rubbish.
They must be collected sep-
arately and disposed of in an
environmentally responsible
recycling system.
Dispose of batteries in an
environmentally responsible
manner
.Take discharged
batteries to a qualified spe-
cialis tworkshop or to a col-
lection point for used batter-
ies.

WARNING
A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases
can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
! Only use battery chargers with a maxi-
mum charging voltage of 14.8 V.
! Only charge the battery using the jump-
start connection point.
The jump-starting connection point is in the
engine compartment (Y page 344).
If, at low temperatures, the indicator lamps/
warning lamps in the instrument cluster do
not light up, it is highly likely that the dis-
charged battery has frozen. In this case, you may neither charge the battery nor jump-start
the vehicle. The service life of a thawed-out
battery may be shorter. Starting characteris-
tics are particularly impaired at low tempera-
tures. Have the thawed-out battery checked
at a qualified specialist workshop.
Never charge a battery which is still fitted in
the vehicle unless a Mercedes-Benz approved
battery charger is being used.
Abattery
charge runit specially adapted for Mercedes-
Benz vehicles and tested and approved by
Mercedes-Benz is available as an accessory.
It permits the charging of the battery in its
installed position. Contact a Mercedes-Benz

Jump-startingBreakdown assistance

Do not use a rapid charging device to start the vehicle. If your vehicle's battery is discharged,
the engine can be jump-started from another vehicle or from a second battery using jump
leads. Observe the following points:
R the battery is not accessible in all vehicles .Ifthe other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or ajump-starting device.
R vehicles with apetrol engine: only jump-star tthe vehicle when the engine and exhaust
system are cold.
R do not start the engine if the battery is frozen. Let the battery thaw first.
R jump-starting may only be performed from batteries with a nominal voltage of 12 V.
R only use jump leads that have a sufficient cross-section and insulated terminal clamps.
R if the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the empty battery a little.
R make sure that the two vehicles do not touch.
Make sure that:
R The jump leads are not damaged.
R Non-insulated parts of the terminal clamps do not come into contact with other metal parts
while the jump leads are connected to the battery.
R The jump leads cannot come into contact with parts such as the V-belt pulley or the fan.
These parts move when the engine is started and while it is running.
